IMPROVEMENT IN BELT-PUNCHS.

Specification forming part of Letters Patent N0. 147,792, dated February24, 1874; application filed December 6, 1873.

To all whom it may concern:

Be it known that I, EDWARD G. PULLIs, of Providence, inthe county ofProvidence and State of Rhode Island, have invented certain Improvementsin BeltAdjusters, of which the following is a specification:

This invention is more especially designed for use in adjusting' thebelts of sewing-ma chines to any desired tension, and, while adapted foradjusting Hat belts, is more particularly intended for round belts, orthose ot' cylindrical or circular crosssection. The invention consistsin a notch or recess formed in the one jaw of a hand punching device, incombina tion with a punch provided upon the other jaw of the instrument,whereby the end portions of a round belt may be firmly held in suchposition that, in the operation of the instrument, holes may be punchedthrough the central or thickest portion of the belt, to receive thehooks4 or fastenings by which the ends of the belt are joined. Theinvention also comprises a novel combination, with theliereinbetbrespecied parts, ot' a blade or knife for cutting andsquaring the ends rot the belt to the requisite degree.

Figure lis a side view of a belt-adjusting device constructed accordingto my invention, as used upon round belts 5 and Fig. 2 is a silnilarview ofthe same as designed for use 'upon flat belts. y

A B are jaws, constructed with handles O, and pivoted together by apivot, a., as shown in the drawings, in such manner that when thehandles are opened or closed, as the case may be, a corresponding'movement is given to the jaws. Upon the jaw A, but at some littledistance from its outer extremity, is ati fixed a blade, D, whichprojects inward, with its sharp inner edge shearing past the angularshoulder b, constituted by the adjacent portion of the jaw B. Nearer theouter extremity of the jaw A, upon the inner side thereof,are providedthe two punches E F.

Formed in the inner side of the jaw B, immediately opposite the punch F,is a transverse notch or recess, j', made preferably with sloping sides.The extremities of the handles O are formed with dat inner surfaces, andin general contour are shaped to form a pair of nippers or pliers, g.

In using the implement, the jaws A B being opened, the end of the belt,whether round or iiat, is thrust between the blade D and the shoulder b,and is cut ott at the requisite length by the shearing action of theblade when the handles are brought toward each other by the hand of theoperator. This done, the ends ofthe belt are punched to receive thefastenings. It' the belt is a round one, it is laid with its end in therecess j', which forms a guide to hold it in such position that thepunch F will pass through it midway between its sides, as indicated inFig. l, when the implement is worked to bring its jaws toward eachother. Ir" the belt be a fiat one, the end is placed between the punch Eand the adjacent end ofthe opposite jaw F, as represented in Fig. 2, andby the operation ofthe jaws the holes are punched singly and insuccession across the ends ofthe belt. Y

The ends of the belt being brought. together, the metallicv hooks orployed in sewing-machine belts are inserted, and are bent to theirplaces and firmly clamped to the position required for the permanentretention of the ends together by the nippers g, applied after the.manner of ordinary gripingpliers.

'Vhatl claim as my invention is The jaw A, provided with the blade D and011e or more punches, `in combination with the jaw B, provided with thenotch f, all substantially as shown, and for the purpose described.
